Mattermost v11.11 adds data spillage exposure tracking as v12.0 breaking changes loom
A side-by-side editorial comparison of Flarum and Double — release velocity, themes, recent moves, and the top alternatives to consider.
Flarum's 2.0 candidates are accelerating, but the feed publishes only a link per tag.
Flarum is eight release candidates into 2.0, with rc.6, rc.7, and rc.8 landing within five days after a gap of roughly seven weeks following rc.5. The feed carries no notes: each entry is a single line pointing at the CHANGELOG.md for that tag, so the content of these candidates is not visible here. The last entry with substantive text was rc.1 in April, which addressed discussion-list and notification query costs.
Double restructures AI pricing with a 93%-cheaper Standard tier, making Ask Double viable at full-book scale
Double is an AI-first accounting platform built for accounting firms managing multiple clients. Over the past two months the product has aggressively extended its Ask Double AI assistant — building workpapers, importing accruals, managing metrics, routing bank transactions from raw PDFs, and now auto-routing queries across a three-tier model stack. The Sep 10 model restructuring is the culmination: with a Standard tier 93% cheaper than Expert and an Auto mode that routes per-query complexity, Double has shifted AI accounting from a premium add-on into an economically viable default across every client account. The interactive financial statement suite — P&L, Balance Sheet, and Cash Flow — is now complete.

Tempo is the only signal this feed supports, and it has clearly changed: three candidates in five days after seven quiet weeks reads as convergence on a final rather than continued development. What is actually changing between candidates cannot be determined from this source without following the linked changelog.
A 2.0.0 final looks near given the candidate cadence, but this feed will not say what it contains.
Double is an AI-first accounting platform built for accounting firms managing multiple clients. Over the past two months the product has aggressively extended its Ask Double AI assistant — building workpapers, importing accruals, managing metrics, routing bank transactions from raw PDFs, and now auto-routing queries across a three-tier model stack.

The interactive financial statement suite — P&L, Balance Sheet, and Cash Flow — is now complete.
Double is building toward a full AI-agent accounting platform, not just a chat interface bolted onto bookkeeping software. The AI Agents private beta (automating recurring tasks on a schedule or event trigger), the MCP/API surface for programmatic control, and the Connections feature (reaching into Slack, Notion, HubSpot) all point to Double becoming an orchestration layer for accounting firms. The model pricing restructure signals that Ask Double is expected to run on virtually every client action, with human review reserved for exceptions rather than the default. The direction is clear: make AI the primary work surface and treat the accounting firm's judgment as the final gate.
The next move is most likely graduating the AI Agents beta to general availability — converting scheduled automation and event-trigger workflows from a differentiated beta into a standard tier feature. Expansion of the Connections library beyond Slack, Notion, and HubSpot is also probable, since cross-tool context is a prerequisite for agents to make decisions autonomously.
